[Bioperl-l] copying Bio::Tree::Tree objects

[Jon manning]

Hi to all,

Is there a simple way of copying tree objects, i.e. not pass by
reference like:

$tree2 = $tree;

keeping node identifiers etc the same? I want to change one copy while
keeping the other to refer back to. I tried using TreeIO to write and
then read in the tree, but this seems to preclude the use of the same
node identifiers, making the comparison tricky.

Thanks,

Jon
